When I was browsing the kde-3.2-alpha screenshots at kde-look.org, I made heavy use of tabs, by middle clicking.  The first crash was when number of tabs was > 16.  KDE Crash Handler doesn't ever catch these for some reason. (yes they've happened before, but I've never secured a backtrace)  This time, I decided to be more carefull.  I opened 16 tabs, then viewed, and saved each screenshot.  X was using 99% of my CPU.  When I was down to two tabs, konqueror crashed.  I am using Qt version 3.2.1.  Backtrace follows:
